Larry, Well, as I said, the is particular amp had two wrong coupling caps installed, a missing transistor and two bad transistors. It took me a lot of time to understand and troubleshoot it due to: 1. I don't do a lot of solid state 2. I only work on amps occasionally so I'm rusty 3. the documentati...

I spent a fair amount of time recently repairing a Session 400 so I'm interested in these amps and their sheer vast power levels. Yes, the power amp stage has a couple legs of power transistors in parallel, so if the current path is broken on one leg, the others are still there and will drive the sp...

OK, well, any 1 megohm, audio taper potentiometer that will fit will work. but you have to match the shaft diameter and style to the existing knob, and match the mounting method to the hole in the chassis, both of these to avoid modifying the chassis, and the of course overall diameter / box dimensi...

Yes, tone controls are usually potentiometers. how is it broken? Is this image correct for the innards of the unit? https://images.reverb.com/image/upload/s--twWJbthT--/f_auto,t_large/v1631651908/vr6q6dc67hgdmi4p9bxq.jpg In this schematic, the tone pot only has two connections: https://bb.steelguita...

I also recorded all the DC bias voltages for all the transistors (except the power TO-3's) and I plan on adding those to the schematic at some point as a public service. If anybody has a good way of getting these onto the PDF schematic, let me know, (I don't have a way of modifying pdf's). We can ad...
